4. If a piece of work or a job is done in n number of days, then the work done in one day = 1/n
5. Total Work Done = Number of Days × Efficiency
6. Efficiency of work done and Time are inversely proportional to each other.
7. M : W is the ratio of the number of men and women which are required to complete a piece of work, then the ratio of the time taken by them to complete the work will be W : M.
8. If W₁ work is done by M₁ people in D₁ days, working T1 hours in a day and W₂ work is done by M₂ people in D₂ days, working T₂ hours in a  day, then the relation between them will be

(M₁ × D₁ × T₁ × W₂) = (M₂ × D₂ × T₂ × W₁)
